i am trying to simulate on "overload alert for a transformer using voice circuit"- i am using a current transformer as current sensor which is connected to controller PIC16F72 in the hardware design for constant checking of current of a transformer and a voice circuit is used. Now while doing simulation using Proteus 8 , i dont know what to use instead of current transformer. for voice circuit i tried a buzzer. can any one please help to solve this.
 

Use a pot which converts I from CT to V in the range of 0 - 5V for ADC input.
 

Yes, When you use CT in hardware then you use a series resistor and take the V across this resistor and feed it to ADC input. So, I through CT is converted to V for measuring by ADC. In Proteus use POT HG model, wiper of POT connects to ADC input. Apply same V to POT which you get across the series resistor is the hardware CT circuit.
 


thank you so muc. i will try it
